MEASUREMENT AND CALCULATION PRINCIPLES

TVO's Corporate Social Responsibility Report is based on the data required by the Global Reporting Initiative (GRI) Standards for the Core option. The reporting principles pertaining to quality in the Global Reporting Initiative (GRI) Standards have been taken into account during the reporting process.

The report covers the operations of the parent company, Teollisuuden Voima Oyj, as well as operations in the whole of Finland by regions. TVO reports accident and training data to some extent also for the personnel in the TVO Group (TVO and Posiva) as well as TVO's contractors. These data are presented in the report with an indication of which personnel they pertain to. The research into the final disposal of spent fuel implemented by Posiva Oy, a company jointly owned by Fortum Power and Heat Oy and TVO, is described in the reporting. Data on the Meri-Pori coal-fired power plant are not included in the Responsibility Report, as the exclusion of the data will not result in any continuous positive or negative material impact being omitted from reporting.

TVO has defined for reporting several Company-specific aspects to complement the material aspects included in the Global Reporting Initiative (GRI) Standards. These aspects describe social responsibility issues that are typical for TVO. The aspects that are material specifically for TVO include acceptance of nuclear power, economic service life of plant units (service life management), decommissioning of nuclear power plants, and continuous improvement of safety attitude and nuclear safety.

The majority of the data presented in the Corporate Social Responsibility Report are based on the data required to be reported to the authorities, which have also been published in TVO's other annual reports (link to Annual Report portal). The occupational health and safety data on the personnel are based on the Occupational Health and Safety Management System, and the other data are based on personnel data collected from the operations of the Company.

As concerns the reporting of economic responsibility, TVO uses in applicable parts the key indicators referred to in GRI Standards and presents in the Corporate Social Responsibility Report some figures obtained from the financial statements process that are not included in the actual financial statements. The amount of carbon dioxide emissions has been verified by an external GHG verification body.

The Corporate Social Responsibility Report 2017 is part of TVO's overall annual reporting. The other reports published in TVO's online Annual Report include:

  • The Report of the Board of Directors of TVO, prepared in accordance with the IFRS standard, and the Financial Statements 2017 report on the financial development of the Company.
